Description

燃油输送单元的压力调节器及该压力调节器的制造方法
技术领域
本发明涉及一种用于机动车的燃油输送单元的压力调节器,该压力调节器具有:阀,用于当接头内的压力高于预设压力时连通所述接头与出口;可移动的活塞;以及薄膜,保持在固定的环形部件上,用于相对于环形部件而密封活塞。此外,本发明还涉及一种制造机动车的燃油输送单元的压力调节器的方法,其中,阀的活塞通过薄膜与固定的环形部件密封地连接。
背景技术
这种压力调节器经常在现有的机动车中使用,用来调节通向内燃机的进料管道中的压力,并在实践中为人所熟知。在此,薄膜夹紧在壳体的两个环形部件之间,并且将活塞上部的区域和活塞下部的区域分开。接头在这里接通到活塞下部的区域中。所需的薄膜的夹紧力一般通过环形部件边缘的卷边产生。
已知的压力调节器的缺点在于,为了将可开启压力调节器的预设压力保持在严格的公差范围内,薄膜尤其在低于0℃的温度范围内的密封性是不够的。通常,压力调节器由于外部边缘的泄漏会完全地失灵。
发明内容
本发明的目的在于,改进开头所述类型的压力调节器,使得确保了薄膜与环形部件之间的可靠的密封。此外,本发明的另一目的在于,提出一种制造该压力调节器的方法,从而保障了薄膜相对于环形部件的特别可靠的密封。
第一目的根据本发明这样实现,即薄膜与环形部件焊接。
通过这种设计方案,薄膜以材料连接的方式与环形部件连接。由此,确保了在低于0℃的温度范围时可靠的密封性。同时也可靠地避免了薄膜与环形部件之间的安置间隙(或者说安置接缝),该安置间隙会在根据本发明的压力调节器的一定工作时间后导致泄漏。因此确保了薄膜和环形部件之间可靠的密封。
当薄膜与活塞焊接时,根据本发明的设计为直通阀的压力调节器能够进一步提高活塞下部的区域与活塞上部的区域之间的密封性。
根据本发明的另一有利的改进方案,当薄膜具有用于阀座的凹部而该阀座设置在所述活塞中时,可以简单地确保在高于预设压力时流体流过活塞。
根据本发明的另一有利的改进方案,当环形部件和活塞都由塑料制成时,能够以非常低的成本来实现薄膜与活塞和环形部件的焊接。
根据本发明的另一有利的改进方案,当制成薄膜、活塞及环形部件的塑料是聚苯硫醚时,能确保焊接接缝的持久的密封性。
根据本发明的另一有利的改进方案,当塑料具有由玻璃纤维构成的添加物时,薄膜、活塞及环形部件都将具有特别高的稳定性。
根据本发明的另一有利的改进方案,当薄膜或与薄膜焊接的部件由激光束可透过的材料制成,以及其他部件各由激光束不可透过的材料制成时,可以以非常低的成本来形成薄膜的焊接接缝。通过这种设计方案,薄膜可以通过激光来焊接。这特别有助于在批量生产根据本发明的压力调节器时降低制造成本。另外,该制造过程可以是自动进行的。
例如,环形部件有可能是对活塞导向的壳体的边缘。然而,为了调节弹簧部件相对于活塞的偏压力,根据本发明的压力调节器的壳体优选由易塑性变形的材料制成。根据本发明的另一有利的改进方案,当环形部件被密封地夹紧在壳体中时,壳体可以由易变形的钢板制成而薄膜由塑料制成。
第二目的,即提出一种制造压力调节器的方法,该压力调节器具有能特别可靠地相对于环形部件密封的薄膜,该目的根据本发明这样实现,即薄膜与环形部件焊接。
因此,可靠地避免了卷边时形成的安置间隙如在已知的环形部件中的安置间隙。根据本发明,薄膜与环形部件以材料连接的方式连接。这将有助于特别在低于0℃的温度范围时薄膜能特别可靠地相对于环形部件密封。在设计为直通阀的压力调节器中,活塞以相似的方法与薄膜焊接。
根据本发明的另一有利的改进方案,当焊接以激光焊接法实现时,根据本发明的方法是非常廉价的。
附图说明
本发明允许多个实施例。为了进一步说明其基本原理,其中两个实施例将在附图中示出并随后说明。图中示出了:
图1是根据本发明的设计为直通阀的压力调节器的纵向截面图,
图2是设计为调节阀的压力调节器的纵向截面图。
具体实施方式
图1示出了根据本发明的设计为直通阀的压力调节器,该压力调节器具有壳体1和可移动地设置在壳体1中的活塞2。压力调节器用于限制机动车的燃油箱中的进料管道(未示出)内的最大压力。壳体1具有由环形部件3隔开而保持一定距离的两个壳体部件4、5。压力调节器具有用于压力管道的接头6及出口7。活塞2借助于设计为螺旋弹簧的弹簧8利用阀座9向阀体10加偏压。
与环形部件3和活塞2连接的薄膜11相对于活塞2上部的区域将活塞2下部的区域密封。由此而确保了,在接头6中存在压力时活塞2为克服弹簧8的力而被加载,并且在高于预设的压力时活塞2被移动,从而使阀座9从阀体10上抬起。因此,在高于预设压力时,燃油可以从接头6穿过出口7流出。壳体部件4、5都由钢板制成,并且通过卷边12(或者说折边)彼此连接。在环形部件3和下部壳体部件5之间的密封环13通过卷边12被施加偏压。上部壳体部件4的用于保持弹簧8的边缘14设计为可塑性变形的,且用于校准压力调节器,进而用于调节使接头6和出口7之间连通的预设压力。环形部件3、活塞2和薄膜11都由塑料聚苯硫醚制成。薄膜11与环形部件3以及与活塞2都以激光焊接法连接。
图2示出了设计为调节阀的压力调节器。该实施例与图1示出的实施例的主要区别在于:从活塞17来看,出口15和接头16设置在同一侧。薄膜18仅仅在径向外侧区域与环形部件19焊接并且覆盖了活塞17的整个横截面。另外薄膜18形成了抵靠到出口15的阀座20上的阀体21。在接头16中存在预设压力时,活塞17和薄膜18从出口15的阀座20处被压开,从而燃油可以从接头16通入出口15。
